67-536-INK 20.0mm Dia. x 50.0mm FL; NIR II; Inked; Plano-Convex Lens NIR II 750-1550nm
The 67-536-INK is a Plano-Convex lens, a type of spherical lens, sourced from Edmund Optics. This lens, with a diameter of 20.0mm, is designed for use in the Near-Infrared II (NIR II) spectrum, specifically for wavelengths between 750 and 1550nm.
The lens features a front and back coating of edm nir-ii std curve, which is specifically designed for use in the NIR II spectrum. This coating enhances the lens' performance in this region, providing superior image quality and light transmission.
The lens has a thickness of 1.84mm at the edge and 4.5mm at the center. The effective focal length (EFL) of the lens is 30mm, and the back focal length (BFL) is 27.3mm. The lens' inner and outer radii are 0mm, indicating a flat surface on the incident side and a curved surface on the refracted side.
The lens is made from n-baf10 schott, a material known for its excellent optical properties in the NIR II spectrum. This material ensures high transmission rates and low absorption, making it ideal for use in applications such as biomedical imaging, night vision, and spectral analysis.
